Application led August 2, 1910. Serial No. 575,170.

The present invention relates to improve` ments in folding'umbrellas,and more particularly to that class in which the ribs, braces andthestaff or stick are composed of .a plurality of slidably engagedsections.

One of the objects of the invention is to simplify and improve theconstruction and and to provide one which is of a very simple, strong,and durable construction, and easy'to operate.

Another object of the invention is to provide an umbrella which may befolded into a very compact and small bundle, which can 'be carried inthe pocket or Satchel, the umbrella being in the form' oa smallcylindrical package only a Afew inches in diameter and a few inches inlength.

With these and other objects in view, which will appear as the inventionis better understood, the same consists in the construction, arrangementand' combination of parts hereinafter fully described, pointed out vinthe appended claims, and illustrated in the accompanying drawings, itbeing understood that various changes may be made in the size andproportion of' the parts, and minor details of construction withoutdeparting from the spirit or sacrificing any of lgheadvantages of theinvention.

One of the many possible embodiments of the invention is illustrated inthe accom-A panying drawings, in which Y Figure 1 is a side elevation ofthe urnbrella stick, one of the ribs and one of the brace pairs oftheimproved umbrella, showing themin their extended or open positions;Fig. 2 is asimilar view showing the rib and the braces in their closedpositions; Fig. 3 is a similar view showing all parts folded orcollapsed; Fig. 4: is a plan view of one of the ribs; Fig. 5 is asection taken on line 5 5 of Fig. 4; and Fig. 6 is a vertical l crosssection ofthe umbrella stick in its ex- -'tended position.

In the present embodiment of the invention, the sta or4 stick iscomposed of six tubular sections 6, 7, 8, 9, i() and il.. @t

these the sections Sand 9 are iixedly attached to each therzand withineach other. while the other sections aretelescoped into the sections 8and '9. t'is,-ot` course, obvious that the stick may consist of agreater or less number of sections. The stick sections are held in.their extended positions, shown in Figs. 1 and 2, by means of. springcatches 12, 12, rlhe spring catch attached.

to section 'rests then upon the upper edge of the section 7, and thespringcatch of thel latter section engages the upper closed ends of thesection S and 9. ln a similar manner rests the spring catch of thesection 9 upon the upper edge of the section 10, and the catch of thesection l() upon the upper edge of the section 11'. The construction ofthese 'spring' catches need not be described, as the saine is well knownin the' art. The disengagement of vthe stick sections from each other isprevented by suitable stops 12. The lower end of the 'stick section 1,1is provided with a suitable handle 13. To the section 7 of the stick issecured a' notch disk 1st, to which the inner ends of the ribs l5 arelpivoted. A notch disk 16 is fastened to the section 8 of the stick, towhich are pivotally attached the inner ends o'j the main stretchers 17,their outer ends being in a similar manner attached `to the ribs 1:3.The runner oi the umbrella is indicated at 18,

'having attached thereto the inner ends oi auxiliary stretchers 15), theouter ends oit which engage pivotally the stretchers 1T.

The rib is formed or' three sections 20, 21 and 22, or' which thesections 2O and 22 are slidably held upon the section 21. This lattersection is of U-shaped cross section, hav ing a partition runningthroughout the length thereof, whereby two channels Qi The section20`and 25 are formed therein. slides into the channel 24, while the section22 slides into the channel 25, when the ribs ci. the umbrella arecollapsed. To prevent the rib section 2O from telescoping into thesection 21, when thc'unihrella is in its open position, a springpressed. locking lever 2G is pivotally attached at 27 to the rib section2l, its nose engaging the end of the rib section 20, while vits iree endpro jects toward the stretcher 17, for a purpose hereinafter to bespecified The rib section 22 is prevented frein telescoping yinto thesection 21 by means of 1a spring stop 30, ii'xedly attached at 30 to therib section 21, and having an inwardly projecting finger 31 engaging theend of the section 22. An extension 32 of the spring stop projects intothe channel 2dr of the rib section 21 and into the path of the end ofthe rib section 20, in -telescoping The stretcher l'ffismade of twosections 33 and 34, which are pivotally secured to gether at 35. Thesestretcher sections and also the stretcher 19 are of U-shaped crosssections, and more particularly the cross'section of the stretchersection 3311s somewhat 14, so that, when the umbre a is being collapsed,the covering can be folded without detachinggthe saine from the frame.,

When it is desired to close the umbrella from its position shown in Fig.1 to that shown in Fig. 2, the spring catch 36 upon the stick section 8is forced into the stick sufficiently to be disengaged from the runner18. The runner can the'n be pulled down-ward toward the handle 13,whereby the umbrella will be closed in the usual manner. v

To open the umbrella, that is tok bring it from the position shown inFig. 2 to that shown in Fig. 1 of the drawings, the runner 18 is takenhold of and pushed toward the notch disk 16, and until the lower end ofthe runner is brought to rest upon the pointed end of the spring catch36.

When it is desired to fold the umbrella, or in other words to reduce itslength shown in Fig. 2 to that shown in Fig. 3, .first the spring catchof the stick section 6 is pressed inwardly, whereby the section-6 can beslid into section 7. In telescoping the section 6 into section 7, thelower end of the former will disengagethe spring catch 12 0j? section 7'fromthe section 8, whereby the section 7 can be telescopcd into thesection 9,'and at the same time the rib section 20 into 'the rib section21. It will be observed that in closing the umbrella from the positionshown in Fig. 1 to that shown in Fig; 2 of the drawings, the stretchersections 33 will force the noses of the locking levers 26 out ofengagfement with the outer ends ofthe rib sections 20, allowing therebythe latter to slide into the sections 21. The outer ends of -the ribsections 2O lift the projections 32 of the spring stops 30, anddisengage thereby the lingers 31 of said stops from the inner ends ofthe rib sections 22, allowing them to slide into the sections 21. Whenthe spring catch 12 upon section 10 of the stick is forced inwardly, thesection 10 can be telescoped into section 11. In this position the bell37 upon section 11 is broughtinto engagement with,

the outer ends of the rib sections 22, after which thesection 10 istelescoped into the Lstick section 8 5 the spring catch 12 ofthe section9 having been previously disengaged.

from thesection l0 as .the section 7 of the stick was telescoped intothe section 9, in the same manner as the section 6 disengages the springcatch of the section 7 from sec` tion 8. The rib sections 22 telescopewith the movement of the stick section 10. `In

order to extend the umbrella, obviously the i reverse operations arenecessary.
